I preferably provide a pair of supplemental siils 1 and 5 mountedona plurality'of.

blocks 6 supported-by the chassis" sills ad jacent the rear end thereof; front ends ofthe sllls be ng secured to a jcrossmember 7 provided with a depending central pivotbar member Smovably mounted in a socket 9 supported by across member lOhaving ends secured {to the chassis sills, detailsofsthefl mounting and the several parts thereof to ,1

be. later particularly described.

I The suppiementalsills 4 and 5 preferably comprise channel members supported edge- .wise by-the chassisjsills with their flanges? 11-directed toward themiddle' line of. the

chassisfand so positioned thatv'their web portions 12 stand .1 adjacent and preferably I-beamsfsecured to.thechannel-likezsupplemental sills and having their end edges welded to the inner faces fj'the'web pore,

Mountedon each of said tran sversemem-,

' here 18 adjacent the ends thereof arepairs' ofgtransve'rsely' spaced pedestal-like brack etsl i' comprising relatively long horizontal baseportions'l5 having'lower faces engag-v ing the uppersurfaces of the cross members 13 and secured thereto, for example by weld-.

ing. The brackets further comprise outwardly laterally projecting arm portions 16 adapted to receive loopedends 17 of saddle l strapvmem'bers 18 for suspendingly support- 7 ing the'tank, and also to receive strap bolts comprising end members 19 of bands 20 adapted to engage the up er portion of'the periphery of the tank ;..er anchoring fthe engaged tank portions to the saddle straps.

The brackets have inclined inner and outer edges or faces 21 and 22, and are further provided with grooves or slots 23 on their inner faces having downwardly inwardly inclined floors 2t and forming ear-like vertical parallel walls 25 which are provided with aligned openings 26 to receive pins 27 adapted to extend through loops 17 of saddle straps 18 for pivotally mounting the ends of the saddle straps on the brackets.

Extending outwardly and preferably at a slight downward angle from the inclined outer faces 22 of the brackets at the upper ends thereof are lugs 28 having openings 29 to admit the strap bolts 19 on which nuts 30 may be screwthreaded to anchor the bands to the brackets.

The cars 25 are preferably extended la erally from the brackets to provide side wall guides for the bolts 19' and are connected at their outer ends by a wall 31, the ears and walls forming guides for the bolts and reinforcing the lugs 28.

The openings 29 are formed larger than necessary to receive the bolts, so that there may be a slight latitude for mounting the bolts in the openings.

The slanting floor of each groove 23 is spaced sufliciently from the pin-r ceiving opening and extends at suitable inclination to permit mounting of the backbent extremity of a strap forming the loop 17 to depend without substantially engaging the bottom of the groove when the strap is deflected downwardly due to the weight of the tank and its contents.

Each bracket is further pro 'ided with a lateral lip-like shoulder or ledge 32 having a lower face 33 substantially parallel with the cross bar engaging bottom surface of the bracket. The shoulder is suitably positioned on the bracket and the cross bar is so secured to the supplemental sill that the shoulder overlies the upper flange of the channel-like sill and serves to brace and reinforce the bracket.

The shoulder member 32 further comprises reinforcing portions 34 extending from the sides of the bracket and the sidewise projecting enlargements preferably extend upwardly to provide thickened portions of the ear members 25 and extensions of said ear members for stiffening and reinforcing the outwardly projecting and inclined arm of the bracket.

Bosses 35 are further formed on the outer faces of said ear portions at the openings for additional bearing support for the pin 27.

The shoulder members 32 are preferably welded to the supplemental sills whereby they cooperate with the welded bases of the brackets for firmly securing the brackets to the supplemental sills.

Extending longitudinally on the chassis sills in the areas of the block-like supports 6 are relatively wide wooden members or boards 36 laid flat on the sills and having side edges projecting laterally from the sills, and plates 37 mounted on the boards receive the block-like members 6. ii-bolts 38 embrace the sills and have ends 39 extending through the boards and plates 37 to receive nuts 40 for clamping and binding the boards and plates to the sills.

The plates 37 further comprise downbent flanges ll overlying the outer side edges of the wooden members and upwardly bent vertical flanges 42 at their opposite edges extending substantially to the lower faces of the cross members 13 and preferably having outwardly bent flanges 43 which may be welded to said cross members 13.

Metal clips or strips 44 are preferably mounted on the inner side edges of the wooden members and may be welded to the vertical l2 to provide a relatively rigid edge wall enclosure for the wooden member.

Bolts 45 are mounted transversely in the wooden members at intervals therealong and may extend through the depending flanges l1 and edge plates all to receive nuts 46, whereby the wooden members are reinforced and hazard of splitting of the same is minimized.

The blocks 6 above referred to comprise strip-like plates or base portions l7 positioned transversely of the plates 37 and preferably secured thereto by welding. The blocks further comprise vertical walls 48 adjacent the outer ends of the bases and adapted to be located laterally from and outside of the planes of the outer faces of the chassis sills and adjacent the outer edges of the wooden members 36 and plates 37. The walls 4'8 are provided with inwardly extending horizontal shelves l9 parallel with the bases and adapted to receive the lower edges of the supplemental sills and are preferably welded thereto.

The shelves are located in spaced relation with the upper edges of the vertical walls 49 to provide keeper-like portions 50 against which the outer vertical faces of the lower edge portions of the sills abut.

The blocks are further provided with vertical rib-like reinforcing and stiffening plates 51 integrally connected with the bases and the vertical walls, extending preferably on the center lines of the bases, the upper edges of the ribs being incut as at 52 for extending beneath the shelves to the vertical walls and to leave a point-like portion, and the outer vertical edges 53 being adapted to engage the vertical flanges 42 of the board covering plates 37.

The members for pivot-ally supporting the front end of the tank, namely the pivot bar Metalstraps'73 are,-.preferablyweldedtothe jundersidesfof lateral flanges-7450f the; brackets 70 and overlie the upper edges of a the supplementalsills for engagement theremember 17' and the: socket 8 will now be more at itsfront edge, the socket member' 9 comprising a base portion 56 having" openings 57 to receive bolts 58 adapted for secur-"y ing the socket member to the horizontal plate 54 on the median line of thechassis." The plate portion 54 of the cross member is relatively wide to provide for a relatively long socket member having a recess or socket 59 comprising a cylindrical elongated opens a ing having its axis mid-Way between the "members and-the tank will' be supported in.

chassis sills and opening upwardly through a rela'tively'wide'longitudinal slot 60 where by a pivot bar 61 secured by aneck 62 to a horizontal plate portion 63 ofthe member 7 maybemOunt-ed-in the socket and may-be relatlvely freely movable therein to permit relative movement between the front end of the tank and the truck frame.

The member 8 further comprises an-up standing flange orplat'e portion '64projecting upwardly fromthe horizontal plateI63' and a downwardlyfprojecting vertical portion 65 comprising a stop Wall against which the front end of the socket member 9 abuts,

L the pivot bar '61 projecting forwardlyifrom said depending vertic'al'wall.

The plate portion 63 of'theimember Sis secured to a horizontal plate portion '66 of the transverse member 7 heretofore referred Toto as secured to the front ends] of the sup-.

plemental sills, and the upwardly projecting v flange 64 of the member 8 is secured to the vertical'flange of said member7;

The structure heretofore described iper- 3 mits the convenientmolinting of other ele ments as will now be set forth. v Can'racks 67 .are preferably supported' on brackets 68 comprising vertical laterallyfpro jecting web portions 69 havingvertical )3 inner edges abutting the outer faces of the supplemental sills, and angle brackets H7O welded to the webs have flanges 71 ovr lying I the supplemental sills and secured With by bolts 75, the straps Ipreferably having downbent inner ends 76 adaptedtoanchor the brackets to the sills. In apparatus constructedas described,-the

blocks having the inwardly extending.

shelves provide for mounting supplemental sills adjacent the outer edges of the chassis sills and therefore in relatively greatly spaced relation so that bracketssupported by the supplemental sills may support saddles of relatively greatlength to provide ters lPatentHis:
